Engine Problems

[hellbound547]

i have a 2002 yamaha blaster and i have a weird problem, the bike wont idle and i can hold the throttle wide open and she spits and sputters, then shuts off, i took the head and cylinder off and every thing looks good, i think it might be the carb. any sugestions?

is your tors still hooked up? try unhooking it and see if that does the trick

 

[coreyownz]

yea i agree with stroker mine wouldnt run for sh*t or it could be ur reeds that also did it for me

What exactly do you have to do to remove the tors?

 

[hellbound547]

i had new boysen reeds put in it about 4 weeks ago and they are good, i dont understand wat tors are.

 

[245stroker]

theres a diy on how to remove the tors unit, it shows you step by step on how to do it.

 

[Braapbraap95]

Its a sort of revlimiter type thing, i dont know exactly what it is. but i do know that they are prone to failure, in which case making your blaster run like sh*t or not run at all.

 

[hellbound547]

wat does the tors do?

 

[hellbound547]

nvm lol throttle over ride system

 

[Braapbraap95]

lol, k you good now? i just read the DIY too. lol

 

[hellbound547]

i took off the tors and there is no difference but every time i take out the plug is all wet, maybe its the carb, the bike wont even offer to start

 

[89custom]

kinda dumb, but you got the choke off right? maybe you just got a rich main jet

 

[hellbound547]

i just took the tors off and there is no difference the bike wont even offer to start, the plug is always wet i think its the carb

 

[hellbound547]

yea the choke is off lol

 

[89custom]

lol sometimes the most obvious things slip cuz u ignore them. whats your main jet?

 

[hellbound547]

the bike was workin fine all along then out of no where it just started to spit and sputter

 

[hellbound547]

umm....not sure stock i'd say

sounds like a jetting issue. weird that she ran before now though.....check your airbox and filter, if there's something constricting airflow, that'll run you rich.
if that's ok, then try to turn out your air screw about 1 turn. this will lean out your mix at idle. also, you might have to increase your idle speed.
once she idles, check the plug to tell if you need to lean out more. then check the plug at full throttle. this will tell you the condition of your main circuit.
if that's good then pull the carb and check everything out.

Same Problem

I AM HAVING THE SAME ISSUE! I already removed the TORS using the DIY thread, nothing changed. i just had the top end rebuilt at a shop, it fires right up, but sputters and slowly dies. it wont idle unless im giving it gas. i then check my plug and it is soaked (brand new plug). it's seems to be flooding itself. i have already thoroughly cleaned the carb about 5 times. the main jet is #230.

i just got thisblaster the other day, it is missing the cage & air filter under the seat. i am thinking this is letting in too much air, but even when placing my hand over the intake hole while its running, it made no change.

any ideas? p.s. the reeds are brand new installed by the machine shop also
